On the L2 continuity of a class of pseudo differential operators
On the L2 continuity of a class of pseudo differential operators
with X, ~o, ~ fixed weight functions on ~+ = {~ER, 4=>0}. Our aim is to give necessary and sufficient conditions for the weight functions i n order that the operators (0-1) are continuous on LZ(R). As a matter of fact, we shall restrict ourselves to the one-dimensional case, n …
